FBICTION HEAT-GENERATOR.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Applicationfxled February 2, 1914. Serial No. 816,013.

To all whom it mag/concern:

Be it known that I, JULIUS H. BECKER, a citizen of the United States,residing in the city and county of San Francisco vand State ofCalifornia, have invented new and useful improvements in FrictionHeat-Generators, of which the following is a specification.

This invention relates to a centrifugally actuated friction heatgenerator.

The object of the present invention is to provide a simple, substantial,easily operated water'he'ater or steam generator for heating' systems,in which smoke stacks and boilers, vwith connected mechanism, may beentirely eliminated.le

The invention'includes a water heater or steam generator in which acentrifugally actuated friction device is employed to generate the heat.

The invention further consists of certain details of construction,combinations and arrangements of parts, all of which will be hereinaftermore particularly set forth and claimed in the accompanying drawings andspeciiications.

Figure 1 is a through the generator. verse section.

i Referring to the drawings, :it indicates a horizontally positionedcylinder, supported by lungs 2 on a suitable bearing` frame 3, and 4t isa water jacket formed integral with the cylinder and entirelysurrounding same. Suitably journaled in bearing member-sf, formed on apair of end plates or heads l and 7, secured to the cylinder, as at 8.is a shaft 9 which extends through the cylinder in a concentric positionwith relation to the innersurface of same.

Keyed upon the shaft, as at 10 and 11, within the cylinder, between theend plates longitudinal vertical section Fig. 2 is a trans- 6 and 7, isa pair of lieXagonal shaped collars 12 and 13, and supported betweensaid collars is a suitable number of bearing rods 14e. lestimer upon theseveral faces of the collars 12 and. 13 and ezrtendiner a sulicientdistance beyond same, to practically reach from end to end of theinterior of thc cylinder A, is a. corresponding number of plates 15,each of which is provided with a downwardly turned, hookisliaped luer 16adapted to engage with the rods 1%-, and secured on the outer face ofeach plate by bolts 17 is a friction shoe 18.

, rhe shaft 9, with connected collars 1i? and 13, plates 15 and shoes 18are revolved as a unit within the cylinder and the shaft may be directlyconnected to an electric motor, or any other suitable driving'mechanism, not here shown. The centrifugal motion thus transmittedforces each shoe 1S out into frictional engagement with the interiorface of the cylinder, and the heat thus generated is radiated throughthe cylinder' 'all to heat the water contained in the jacket or for thepurpose of generating steam.

The pivotal mounting of each friction shoe, which is produced by theconnection formed between the rods 1l and the hookshaped lugs 16, allowseach shoe to contact and seat itself upon the interior surface of thecylinder. A perfect contact between the friction shoe and cylinder isthus made and the highest friction eliiciency produced. Any wear orvariation in the hardness of the material of the friction shoe is thusautomatically taken up and adjusted one independent of the other. Theoutside surface and ends of the cylinder may be covered with a suitableform of heat-insulatingr material and practically all losses, byradiation` in this manner may thus be prevented.

The capacity of the generator constructed as here shown may be greatlyincreased or decreased to suit variousv conditions by simply incre: singor decreasing; the number of friction shoes carried upon the collars lf2and 13. The friction surface is thus reduced or increased with aconsequent change in heatingr or gfeneratiimT capacity within the jacket4, and a standard size of unit may thus be employed, thc eapacity ofwhich may be greatly varied to suit various conditions.

The Agenerator operated in the manner here shown eliminates all dangersof lire, and the cost of installation is very small, comparfnl with thcstandard heating plants now employed, as burners, smoke-slacks andboilers, with the connected parts, are en* tirely eliminated.

The materials and finish of the several.y

parts of the generator are such as the e5;-

' l the cylinder, a rotor Within the cylinder secured tothe shalft, anda plurality of friction members engageable with the interior surface ofthe cylinder mounted in the rotor. I 2. A friction heater and steamgenerator comprising in combination, a water-jacketed cylinder, adriving shaft extending through the cylinder', a rotor within thecylinder secured to the shaft, and a plurality of friction shoesengageable with the interior surface of the cylinder pivotally mountedon the rotor.

'3. A friction heater and steam generator comprising in combination, awater-jacketed cylinder, a driving shaft extending through the cylinder,a pair of disks secured to the shaft spaced with relation to cach otherand the ends of the cylinder, a plurality of rods carried by the disks,and a plurality of friction shoes engageable with the interior surfaceot the cylinder pivotally mounted on said rods. l y

4l. A friction heater and steam generator comprising in combination, awater-jacketed cylinder, a driving shaft extending through the cylinder,a pair of disks secured to the shaft spaced with relation to each otherand the ends ofthe cylinder, a plurality of rods carried by the disks, aplate pivotally `secured on one edge to each rod, and a friction shoesecured on each plate adapted to be thrown into engagement with theinterior surface ofthe cylinder by centrifugal action.

5. A friction heater and steam generator comprising in combination, aWater-jacketed cylinder, a driving shaft extending through the cylinder,a pair of disks secured to the shaft spaced with relation to each otherand the ends of the cylinder, a plurality of rods carried by the disks,a plate pivotally secured on one edge to each rod and radiallyadjustable upon same, and a friction shoe secured on each plate adaptedto be thrown into engagement with the interior surface of the cylinderby centrifugal action.

In testimony whereof I have hereunto s'et my hand in the presence of twosubscribing witnesses.
